Proxmox Hide Virtualization | How-to

Did you know Proxmox offers a feature that allows us to hide virtualization?

In order words, we can conceal the underlying virtualization platform used by Proxmox Virtual Environment from within the guest virtual machines.

As such, the guest VMs assume they are running on bare metal rather than being aware that they are running inside a virtualized environment.

This feature comes in handy in certain scenarios, like when we want to run software or applications that have limitations or restrictions when running in a virtualized environment.

When we hide the virtualization, we can bypass these limitations and make the software believe that it is running on a physical machine.

According to our experts, we can hide virtualization via the “KVM CPU model passthrough” feature.

KVM is the underlying hypervisor used by Proxmox for virtualization. By enabling CPU model passthrough, Proxmox allows the guest VMs to detect and utilize the actual CPU model and features of the physical host, making them less aware of the virtualization layer.

How to enable CPU model passthrough

1. First, check if the host CPU supports the necessary virtualization features, like Intel VT-x or AMD-V.
2. Then navigate to the settings of the VM we want to configure in the Proxmox web interface.
3. Next, head to the Processor section under the Hardware tab and choose the “Copy host CPU configuration” option. Alternatively, we can choose the desired CPU model from the list.
4. This step is optional since some software or applications may still detect the virtualization layer even with CPU model passthrough enabled. In these scenarios, we have to modify the guest VM’s configuration or install additional tools to disable hypervisor detection.
